Product Overview

The LTC3786EUD#PBF is a high-performance synchronous boost Converter Controller that drives all N-channel power MOSFETs. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the LTC3786 to be used in high power boost applications. A 4.5 to 38V input supply range encompasses a wide range of system architectures and battery chemistries. When biased from the output of the boost converter or another auxiliary supply, it can operate from an input supply as low as 2.5V after start-up. The 55μA no-load quiescent current extends operating run time in battery-powered systems. The operating frequency can be set for a 50 to 900kHz range or synchronized to an external clock using the internal PLL. It features a precision 1.2V reference and a power good output indicator. The SS pin ramps the output voltage during start-up.
  • Synchronous operation for highest efficiency and reduced heat dissipation
  • ±1% 1.2V Reference voltage
  • RSENSE or inductor DCR current sensing
  • Adjustable output voltage soft-start
  • Power good output voltage monitor
  • <8µA Low shutdown current
